What can cause pelvic pain in a female?

Pelvic inflammatory disease (PID) is an infection of the female reproductive organs. It usually occurs when sexually transmitted bacteria spread from your vagina to your uterus, fallopian tubes or ovaries. Pelvic inflammatory disease often causes no signs or symptoms. As a result, you might not realize you have the condition and get needed treatment. The condition might be detected later if you have trouble getting pregnant or if you develop chronic pelvic pain. If your pelvic pain may be caused by weakened pelvic muscles, try doing Kegel exercises.If you are experiencing unusual pelvic region pain along with vaginal bleeding, call your doctor immediately, especially if you are, or may be, pregnant. This can be a sign of a miscarriage or gynecologic condition.
